Groin Pressure/Pain

So I’m 36 weeks preggo, I know baby has dropped about two weeks ago. This week though I have been experiencing vaginal pressure I guess? It feels like I’ve been riding a bike for 7 hours straight.. I’ve heard it’s normal but I also can’t find any information on it and what it means. So, any moms reading this, could you explain why this is? And did you experience it? Could it mean I’m trying to dilate or is it just because he’s so low and engaging and ready to make his appearance?
